Cossatot River Bridge Improvements
The Cossatot River at Ed Banks Crossing design involved the renovation of a low water bridge on a National Wild and Scenic River. The bridge design features are cast-in-place piers and precast concrete bridge decking. The bridge functions as a low water bridge during high flow events. PMI completed HEC-RAS modeling of the Cossatot River in the area of the crossing and applied for applicable regulatory permits. The bridge was constructed in July-October 2017. PMI received an ACEC Arkansas Engineering Excellence Award for this project in 2018.
